Abstract Computing and using opacities is a key part of modeling interpreting data exoplanetary atmospheres. Since the underlying spectroscopic line lists are constantly expanding currently include up to ?10 10 –10 11 transition lines, opacity calculator codes need become more powerful. Here we present major upgrades HELIOS-K GPU-accelerated describe necessary steps process large within reasona...

The serum opacity factor (SOF) is a group A streptococcal protein that induces opacity of mammalian serum. The serum opacity factor 22 gene (sof22) from an M type 22 strain was cloned from an EMBL4 library by screening for plaques exhibiting serum opacity activity. DNA sequencing yielded an open reading frame of 3,075 bp. Its deduced amino acid sequence predicts a protein of 1,025 residues with...

Opacity is an important system-theoretic property expressing whether a system may reveal its secret to passive observer (an intruder) who knows the structure of but has only limited observations behavior. Several notions opacity have been discussed in literature, including current-state opacity, k-step and infinite-step opacity. We investigate weak strong that generalize both ask intruder not a...

deinkability of old newspaper was investigated using cellulase at different concentrations and treatment times. the results of optical properties of the made papers indicated that by increasing the enzyme concentration to 0.05 percent the brightness was increased to 47.5% iso and yellowness decreased to 11.03% iso. while at higher charges than 0.05 percent, brightness value the was decreased an...

Primordial baryonic matter in the vast intergalactic space may be traced with Lyα resonance absorption by neutral hydrogen and singly ionized helium. The wavelengthaveraged He ii opacity shortward of 304(1+z) Å, as measured by low-resolution UV spectroscopy, is at least 4.5 times the H i opacity shortward of 1216(1+z) Å. While a part of the He ii opacity arises from the intergalactic regions th...

Purpose. To evaluate Fourier-domain optical coherence tomography (FD-OCT) as an adjunct to traditional slit lamp examination of donor corneas with suspected Anterior Stromal Opacities. Methods. Seven corneas suspected of having anterior stromal opacities by slit lamp examination were evaluated with FD-OCT. Each cornea was evaluated to confirm the presence of opacity and, if present, the depth o...

We study in depth the class of games with opacity condition, which are two-player games with imperfect information in which one of the players only has imperfect information, and where the winning condition relies on the information he has along the play. Those games are relevant for security aspects of computing systems: a play is opaque whenever the player who has imperfect information never ...

PURPOSE To determine whether critical flicker/fusion (CFF) thresholds fulfill the criteria for a potential vision test (PVT) by being unaffected by media opacity yet affected by retinal disease. METHODS CFF thresholds for three different stimulus sizes (0.5, 1.0, and 1.5 degrees ) were measured in 72 patients (mean age, 78.43 +/- 7.07 years) comprising 31 subjects with media opacity, 21 with ...

The opacity of a bacterial suspension is measured by the length of the column of the suspension required to cause the disappearance of a wire loop. By a simple formula the measured opacity is translated into terms of the concentration of bacteria per cc., and so made comparable with that of other suspensions of the same organism. An instrument for measuring the opacity of bacterial suspensions ...

We describe the class of games with opacity condition, as an adequate model for security aspects of computing systems. We study their theoretical properties, relate them to reachability perfect information games and exploit this relation to discuss a search approach with heuristics, based on the directing-word problem in automata theory.
